onKeyDown

var InputDemo = React.createClass({    getInitialState: function() {        return { message: ''        };    },    onKeyDown: function(e) {        if (e.keyCode === 8) { console.log('delete');        }    },    handleChange: function(e) {        this.setState({ message: e.target.value        });    },    render: function() {        return ( <div>     <input         value={this.state.message}         onChange={this.handleChange}         onKeyDown={this.onKeyDown}     /> </div>        );    }});
